Scientists have developed and tested a “DNA robot” that delivers payloads such as drug molecules to specific cells.

The container was made using a method called “DNA origami”, in which long DNA chains are folded in a prescribed way.

Then, so-called aptamers - which can recognise specific cell types - were used to lock the barrel-shaped robot.

Science has indeed caught up with reality.

Ships’ propellers emit sound in the same frequency range that some whales use for communicating, and previous studies have shown the whales change their calling patterns in noisy places.

Now, researchers have measured stress hormones in whale faeces, and found they rose with the density of shipping.

There’s only one man who can help these whales now…
